A set or reman bosch injectors on ebay is about 96-110 bucks. They worked well, i did 3x already incase you go this direction thats why i asked what codes are you having. Once you get your code reader, it will be easy. It will be good since you almost have replaced most parts. Cheers.

Ok, so I coded the truck.
p0102. MAF low voltage (new MAF installed)
p1590 3 amigos
p0453 fuel sensor high voltage (new non-SAI fuel pump on a truck with a SAI wiring harness tank plug, but no SAI on engine....). I left it unplugged.
p1300 detonation
p0303
po305
p0307
So I have misfires on the entire right bank (cleared P0301 at the start).
It cant be coils as they are double fed (and new).
The MAF code could be from corroded contacts. I’ll clean those tomorrow.
Any ideas?

Could it be something as simple?
ill order one.
I wonder if the wife took it off road and yanked the sensor wires...and failed to mention. Wouldn’t be the first time...she treats it like a tractor at times.
i hated changing the left upstream...that connector is a pain.
Thanks for the input.

Update. I replaced the upstream O2 sensor on the left bank. The rough idle, wont maintain rpms, no power....it's all still there. New MAF, new Idle control, TPS, cleaned the throttle body, new air filter, plugs, wires and coils.
Codes: P1300, 301, 303, 305 & 307. flashing engine light when on the gas.
I drained the capacitors to remove the learned trims. The only improvement is it now will stay at idle and not die.
The coils have to be good or I would get misfires on both banks, same with the timing.
I'm at a loss.

Ugh.
Still seems to me that the fact all the misfires are on one side should be a clue. That's why I wrote about the O2 sensor. That's the only thing shared by all four cylinders on either side, isn't it? What are we missing?

mnl01-
The upstream O2 sensor wasn’t that bad to change. I cut the wires close and box wrenched it out pretty easy. The plug on the reinstall was a real bitch! I was real surprised when it came loose from the wiring harness so easy. Turns out I couldn’t get the new sensor to lock into the harness, the locking tab was broken. I had to tape it.
The last time I changed it was about the same.
I swear technology will ruin us all. I should go back to a good old 70’s Chevy V8.

Disco Mike is long gone from this forum.
So. Sounds like there may be issues with the O2 connector. That means I still wouldn't rule out the O2 (and its connector) as the problem.
Again, the O2 is the only thing I can think of that is common to all the cylinders on either bank of the engine. Perhaps try disconnecting, cleaning and reattaching the O2.

The connector was clean at the replacement. If I thought for a moment that I didn’t have a good connection, I would have regrouped and tackled it again.
This wouldn’t be the cause from the start. I never got a code and it has been consistent up to this point. I promise you... they are mated, no click, but taped good.
